ABSTRACT

An aircraft equipped with peripherally configured directional thrust capability has an onboard primary power source producing compressed air, and at least two thrust producing modules. Each thrust producing module has a fuel source and receives compressed air from the primary power source. Each module is attached to a respective rotatable support structure for independently varying the thrust angle of the thrust producing module with respect to the aircraft, all thrust producing modules being connected to a common controller for coordinated control of the aircraft.

BACKGROUND

1. Field of Invention

This invention relates to the field of aeronautics and jet/rocket propulsion systems and, in particular, to integrated, multiply vectorable jet/rocket propulsion systems incorporating all essential aspects of airborne operations including, but not limited to, the functions of propulsion/steering/stabilization as well as, braking, hovering, and VTOL and STOL operations.

2. Background

It is very difficult to make anything more than general, segmented comparisons between the Variably Angled Propulsion/Steering System (V.A.P./S.) and other V/STOL, and/or thrust vectorable propulsion systems because the V.A.P./S System is a revolutionary departure rather than evolutionary, or variant in nature. In conventional thrust vectoring V/STOL systems there are many arrangements, yet represented within each is a common thread—that of venting and/or channeling whereby the jet thrust must, by necessity, lose force and escape velocity as the fluidity of the exhaust flow is deflected with vanes of some sort, or disrupted in the passage through ductwork, being neither direct, nor immediate, resulting in kinetic and thermogenic losses due largely to flow convection, conduction, and resistance by the inner surfaces of the ducts, tubes, channels, vanes, etc., as the exhaust makes its way to its ultimate point of exit.

Bearing this in mind, let us begin with those V/STOL jet propulsion systems utilizing venting methods. This general arrangement, whereby thrust is produced and redirected through means of deflection so as to apply the force of the jet thrust in more than one direction is typified in U.S. Pat. Nos. 4,000,854; 4,241,876; 5,390,877; 6,036,142; and 6,318,668 B1. The other commonly applied method of vectoring jet thrust is by way of channeling the jet thrust, which is produced in one location, and travels to another location where it would typically escape through a moveable exhaust outlet is typified in U.S. Pat. Nos. 3,986,687; 4,456,203; 4,587,804; 4,913,354; and 5,170,964. This method generally provides a wider variety of exhaust positioning and with more control than venting/deflecting, but the thrust is prone to even greater frictional and thermogenic losses, than would occur with venting, reducing power, escape velocity, and overall efficiency to an even greater extent. U.S. Pat. Nos. 4,358,074; and 5,769,317 are examples of how both methods are used together.

Another critical element missing in previous jet propulsion systems is the ability to simultaneously allocate available thrust in any ratio towards the functions of both steering and stabilization. The result of this deficiency is decreased maneuverability. The reason for this decreased maneuverability is forward momentum. If an aircraft traveling at a rapid rate attempted to suddenly and sharply change direction the accumulated force of momentum that had been an essential asset while propelling it from behind would become a potentially fatal liability as the momentum exerted its force against the aircraft's side (imagine the feeling that one receives in an automobile when turning too sharply at a high rate of speed, multiplied many times over, and without even the slight mitigating effect provided by a ground based suspension system). To prevent what would be an uncontrolled and violent tumble, current jet propulsion systems force the aircraft to first reduce speed, bank with ailerons and then raise elevators (even with the assistance of vectored thrust) bringing the aircraft about in a looping manner.

The speed and angle of the turn are further decreased due to the distant placement of the cockpit in relation to what would loosely be referred to as the axis of rotation (the tail assembly). The further an object is from the point of rotation, the faster it must travel relative to that point. The faster an object travels, the greater the gravitational forces generated and accordingly the impact therefrom. So bringing all of this together we currently have thrust vectoring propulsion systems that utilize kinetic and thermal energy inefficiently by virtue of the methodology employed, and force the aircraft to which they are applied to reduce speed, reorient the pilot in an unnatural sideways position, and loop through turns with the pilot in the worst possible position (with respect to “G” forces and also field of vision).

SUMMARY OF THE INVENTION

The invention is illustrated in an aircraft characterized by a relatively low profile with no vertical stabilizer(s) and/or rudder(s) necessary and a fuselage of expanded width having a curvature from front to back and side to side, lending to the aircraft additional lift area as well as providing a very stable platform in order to compliment the dynamic performance of a Variably Angled Propulsion/Steering System (V.A.P./S.). The way the V.A.P./S System works is to bring all of the “raw” ingredients necessary to the production of jet/rocket thrust (compressed air and/or liquid oxygen, fuel, and means of ignition) separately to the point at which they will be utilized—the V.A.P./S. Burner Unit (11), which is itself both variably angled, via the V.A.P./S. Unit Extension Shaft (10), and fully rotatable. The result is unimpeded exhaust flow (more power) with undiminished thermal value (more escape velocity) applicable on any plane and in any direction. As this is accomplished without any sort of channeling (except for the Rear Exhaust Unit [FIGS. 5A, 5B] which is supplementary) or venting, power, speed, fuel efficiency and range would, therefore, be maximized. Further enhancing the efficiency of the Burner Unit(s) (11) and the Rear Exhaust Unit [FIGS. 5A, 5B] within the purview of the V.A.P./S. System, is a V.A.P./S. Unit Variable Area Exhaust Nozzle [FIG. 4] (38B), and a Rear Exhaust Unit Variable Area Exhaust Nozzle [FIGS. 5A, 5B] (43) which utilize the jet thrust in the most efficient way throughout every phase of operation. The V.A.P./S. System will apportion thrust, when turning, such that whatever counter-rotational torque is needed to neutralize momentum will be applied by virtue of the angling of its Extension Shafts (10) and the rotation of the Burner Units (11) [FIGS. 2A, 2B, 3].

The remainder of the thrust is applied towards redirection. Aiding in this endeavor is the remote lateral placement of its relatively light Burner Units (11) [FIGS. 1, 2A, 2B, 3] providing mechanical leverage against the largely centralized mass of the craft, as well as the Burner Units' Variable Area Exhaust Nozzle(s) [FIG. 4] (38B) which varies the combination of exhaust escape velocity versus exhaust escape mass in any ratio providing maximum speed during forward propulsion, and maximum power/torque during vertical takeoff/landing, braking, hovering, and sharply angled, high speed maneuvers.

The V.A.P./S. System, which utilizes the kinetic and thermal energy of the exhaust gasses more efficiently than current thrust vectoring systems, allows the aircraft to which it is applied to enter sharply angled maneuvers at high speed, and to further increase thrust output making more power available to redirection and stabilization and allowing the aircraft to accelerate through the maneuver while the pilot remains oriented in a fully level position and receiving the minimum “G” forces possible due to the placement of the Cockpit [FIG. 1](3). The decentralized configuration of the V.A.P./S. System, versus an identical arrangement, but where the entire engines are positioned in a similar manner as the V.A.P./S. Burner Units [FIG. 1] (11), is advantageous due to the lightweight nature of the V.A.P./S Burner Units (11) wherein the heaviest components necessary to the sustained production of jet thrust (turbine shaft(s) and blades, compressor shaft(s) and blades) are remotely located, closer to the Central Axis of Rotation [FIG. 3] (13), where there is greater structural support, providing a mechanical advantage in leverage with regards to steering and stabilization, as well as better balance, greater responsiveness, fewer maintenance issues, and therefore better overall performance, safety, and economy.

Also to be considered is the human tolerance of gravitational forces; It is one of the primary limiting factors in extreme maneuvering of aircraft in the context of manned flight.

G-forces on the pilot are minimized to their lowest practical level by positioning the Cockpit (3), and therefore the pilot, at the Central Axis of Rotation [FIG. 3] (13) where the rotational speed is its lowest with only a slight off-set so that the pilot can maintain spatial orientation. The off-set occurs as the pilot is so positioned that the balance mechanisms of the inner ear and brain are in line with the Central Axis of Rotation [FIG. 3] (13) and the eyes are just beyond it maximizing the benefits of the robust maneuverability provided by the V.A.P./S. System. Additionally, if low-orbit, trans-global deployment is to be part of the mission repertoire of a V.A.P./S. equipped aircraft, then a highly heat reflective/deflective coating/layer should be present, at the very least, on its underside in order to make re-entry feasible. It shouldn't be necessary to use heavy tiles because the speed, and attitude of re-entry can be controlled with the V.A.P./S. Burner Units in rocket mode.

The V.A.P./S. System is an independent, yet coordinated array of Burner Units (11) positioned, in one preferred embodiment, in a front-left, front-right, rear-left, rear-right configuration [FIG. 1]. The Burner Units (11) are each attached to the fuselage of an aircraft via the variably angled V.A.P./S. Unit Extension Shaft(s) (10) [FIGS. 1, 2A, 2B, 3], the angular setting of which is effected by the V.A.P./S. Angling Unit [FIGS. 8A-8C] (even during flight) which determines the proportion of jet/rocket thrust, produced by the Burner Unit(s) (11) [FIGS. 2A, 2B], allocated to steering versus stabilization during maneuvers. The variably angled V.A.P./S. Unit Extension Shaft (10), when combined with the fully rotatable Burner Unit (11), allows thrust to be vectored in any direction and on any plane [FIGS. 2A, 2B, 3]. Because the Burner Units (11) are offset from the central mass there is the additional mechanical advantage of leverage in neutralizing the destabilizing forces of momentum encountered during sharply angled, high speed maneuvers [FIGS. 2A, 2B, 3].

The Burner Units (11) receive a variable flow of compressed air [FIGS. 10, 11A], as determined by the primary CPU, produced by the Extended Length Primary Jet Engine(s) (4) [FIG. 1] which is able to divert much, if not most, of its compressor output to the Burner Units (11) via the V.A.P./S. Air Distribution Unit [FIGS. 11A, 1I B] and the V.A.P./S. Air Intake Feed [FIG. 10]. It is possible for the Extended Length Primary Engine(s) to do this and still maintain an effective power cycle because far more power than necessary to sustain its own power cycle is extracted by the extra sets of blades on its Turbine Shaft [FIG. 9A] (64). This extra power is utilized by the Turbine/Compressor Gearings [FIGS. 9A, 9B] which, via the Multiplying Gear(s) (66), Turbine Intermediate Gear (67), and the Compressor Gear (68) [FIGS. 9A, 9B], cause the Compressor Shaft (65) to revolve significantly faster than the Turbine Shaft (64) [FIG. 9A] producing far more compressed air faster than it would revolving at a 1:1 ratio. This excess compressed air is delivered to the V.A.P./S. Burner Units (12) where it is used to produce thrust that is more applicable to a wider array of functions than would be the case were it to be burned and vented by conventional jet power plants. The advantages to such an arrangement are as follows: (1) less negative torque is exerted against the aircraft during turning maneuvers; (2) significant quantities of compressed air become available for the production of thrust, within the Burner Units [FIG. 4] (11), where the thrust may be applied towards many performance enhancing functions such as integrated and variably proportioned steering/stabilization [FIGS. 2A, 2B, 3], vertical takeoff and landing and hovering [FIG. 6A], transitional and full propulsion [FIGS. 6B, 6C, 6D], and braking [FIGS. 7A, 7B, 7C, 7D, 7E].

The vast majority of the compressed air flowing into the Burner Unit(s) (11) is used to produce thrust, as would be expected, but a very small amount of that air is utilized to effect the production of electrical current locally, within each Burner Unit (11), via a small Turbine (22) which powers an Alternator or Generator (23), the current from which providing the energy to run all of the devices and mechanisms within each Burner Unit (11) requiring current [FIG. 4]. The major advantages to such an arrangement are as follows: 1. the elimination of the need for a hard-wire connection to the Fuselage [FIG. 1] (1) thus facilitating a complete range of motion by the V.A.P./S. Unit Extension Shaft (10) and the V.A.P./S Burner Unit (11); 2. the elimination of the need for regular maintenance and replacement of an extensive wiring arrangement for each Variably Angled Propulsion/Steering Unit (12); and 3. the elimination of the risk of premature interaction between the current and the air/oxygen and/or fuel supply (especially due to fraying of the wires) [FIG. 4]. Once within the Burner Unit (11) the compressed air is combined with fuel that is delivered by way of a Double-Walled Vacuum Fuel Line [FIG. 4] (37A) which when combined with the V.A.P./S. Fuel Line Joint [FIG. 13] (86) provides a leak-proof delivery system.

The mixture is then burned within the Combustion Chamber(s) [FIG. 4] (38) which are situated in proximity to the V.A.P./S. Variable Area Exhaust Nozzle (38B) [FIG. 4] such that the optimal balance of full combustion and maximal energy conservation is achieved, resulting in greater thrust and higher escape velocities (because the Burner Units (11) are fully rotatable and variably angled via the V.A.P./S. Unit Extension Shaft (10) [FIGS. 2A, 2B, 3,], thrust is immediate and direct as it may be vectored in any direction without channeling or venting.). Furthermore, the V.A.P./S. Exhaust Nozzle (38B) is variably sizeable due to an adjustable V.A.P./S Exhaust Piston (34) which further adds to the efficient utilization of the thrust in every possible situation much in the way a transmission would function [FIG. 4].

Supplemental to the V.A.P./S. Unit(s) (12) [FIG. 1], is the Rear Exhaust Unit [FIG. 1] (8), [FIGS. 5A, 5B] into which the expanding exhaust gasses from the Extended Length Primary Jet Engine(s) (4) [FIG. 1] flow, after having passed through all of the sets of turbine blades, yet still containing enough energy to assist in VTOL and STOL operations, flight mode propulsion, acute attitude adjustments, braking, and hovering completing the totality, when combined and coordinated within the V.A.P./S. System, of a full range of vectoring possibilities on every plane in infinite combinations. The Rear Exhaust Unit [FIG. 1] (8) is also equipped with a Rear Exhaust Unit Variable Area Exhaust Outlet (43), an Electrified Input Track (46), and a Feedback Track (45), the former supplying uninterrupted current and the latter providing constant two-way communications with the primary CPU, both throughout the full range of possible movements by the Rear Exhaust Unit [FIGS. 5A, 5B].

Added to all of the preceding is the capacity to replace compressed air with liquid oxygen via the V.A.P./S. Liquid Oxygen Feed Line [FIG. 4] (41) making low orbit, trans-global deployment a real possibility. Liquid Oxygen could also be fed into the Combustion Chambers (38) of the Burner Units (11) [FIG. 4], with the correct amount of additional fuel, supplementing the compressed air, for hyper-bursts of speed and power, if needed, to both attack opposing forces and evade incoming missiles. While most state of the art aircraft rely primarily on various forms of jamming and countermeasures to thwart these missiles, any suitable aircraft to which the V.A.P./S. System is applied, while possessing the same, would be even more survivable for the following reasons: 1. multiple exhaust sources each leaving different and constantly changing trails (a very effective built-in countermeasure in and of itself); 2. available hyper-speed wherein compressed air is supplemented with liquid oxygen; 3. the V.A.P./S Exhaust Piston [FIG. 4] (34) and the Rear Exhaust Piston [FIGS. 5A, 5B] (42) assists the V.A.P./S. System in accelerating any suitable craft to which it might be applied quickly and to great speeds; 4. the inherent ability of a suitable V.A.P./S. endowed aircraft to make near 90 degree turns at high speed and with complete stability. The result is aircraft that can hit without being hit which is the ideal standard for any combat aircraft.

Taking into consideration the limits of human endurance, the pilot is precisely positioned so as to be nearly at the Central Axis of Rotation (13) as is possible [FIG. 3] (the point at which rotation is slowest and gravitational forces are their lowest) with the balance centers of the inner-ear and brain aligned with the Central Axis of Rotation (13) and the eyes slightly off-set just enough so the pilot can perceive the turn and the extent of the turn.

Applications

The V.A.P./S. System is ideally suited to any aircraft where VTOL/STOL capabilities, and/or superior performance is advantageous such as, but not limited to, craft geared towards air to air combat, air to ground attack, frontline troop deployment and support, Med-Evacs, and even trans-global deployment, making the V.A.P./S. System far more versatile, and with far greater performance, than any version of the JSF or the F-22. In cases where extreme maneuvering on a great multiplicity of planes is not required, the V.A.P./S. System may be “stepped down” and simplified (especially with the removal of the V.A.P./S Extension Shaft) yet still maintaining the essence of the core design of the Burner Unit(s). Examples of such aircraft to which this solution would be ideal are large transports, reconnaissance aircraft, or even purely commercial aircraft needing nothing more than an efficient means to reduce the distance needed to takeoff and land ever increasingly large planes on runways that, in many airports, simply have no room in which to grow, and with the added advantage of increased speed, fuel efficiency, and range.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT

As is well known in the art, aircraft control is characterized by reference to three axes of rotation; the longitudinal or roll axis, the vertical or yaw axis, and the lateral or pitch axis. The precise location of each axis on the aircraft at a given point in time is a complex function of the center of lift or pressure acting in that axis, the center of mass, and the thrust moment of the aircraft thrust systems. The locations of these three axes are normally variable with aircraft configuration, loading, and instantaneous flight dynamics, but typically fall each within its respective, predictable, limited range for the normal flight envelope of the aircraft.

By design of an aircraft, it can be arranged that the three ranges substantially intersect so as to define a nominal center of rotation where acceleration due to rotation of the aircraft in any axis is minimal. However, the invention contemplates the availability and use of asymmetrical and variable direction thrust control, providing the required thrust moment for maintaining a tightly controlled center of rotation while at the same time executing more extreme flight maneuvers.

The V.A.P./S. System may possess a number of sub-systems which collectively enable the overall function of the V.A.P./S. System and are therefore to be considered as part of the overall V.A.P./S. System. They are disclosed and described within the following sections.

FIG. 1-V.A.P./S System—(Top View)

-   Fuselage—being wider than normal with a largely flat underside and a     topside with a longitudinal curvature extending from front to back     and lateral curvature extending from side to side, it provides extra     lift area while reducing turbulent airflow. #1 -   Wing (with aileron) #2 -   Cockpit—located at the Central Axis of Rotation, the pilot is     positioned so that the balance centers of the inner ear and brain     are as closely aligned as is possible with the Central Axis of     Rotation causing the eyes to be slightly offset so that     gravitational forces upon the pilot resulting from sharply angled,     high speed maneuvers are minimized while the ability to perceive the     turn and the extent thereof are preserved. #3 -   Extended Length Primary Jet Engine—extends the full length of the     aircraft to accommodate extra sets of turbine blades so that more     power is available to drive extra sets of compressor blades which     are connected to the drive shaft via multiplying gears which cause     the compressor blades to spin more than once for every revolution of     the drive shaft. This facilitates an increased air supply which is     diverted to the Air Distribution Chamber which supplies the     V.A.P./S. Burner Units with compressed air. #4 -   Jet Engine Exhaust Feed—even after the rapidly expanding gasses pass     through the extra sets of turbine blades, there will still be     significant thrust available for the Rear Exhaust Unit to effect     propulsion, climbing, and diving, and to assist in VTOL/STOL     operations. This makes elevators unnecessary, though it may be     desirable to include them if they can be shown to compliment the     attitude adjustment of the aircraft. #5 -   Rear Exhaust Unit Feedback Track—this interface allows the Rear     Exhaust Unit to rotate while maintaining constant communications     with the CPU. The CPU is able to know the position of the Exhaust     Piston due to a sensor placed in contact with the Exhaust Piston     Rack. A signal is then returned to a switch through which electrical     current from the Rear Exhaust Unit Electrical Input Track must pass.     The switch will route the current to the Rear Exhaust Unit's     electrical motor so that it will cause the actuating gear to spin in     either direction thus effectively and immediately causing the     Exhaust Piston (and therefore exhaust nozzle volume) to be adjusted     as needed. #6 -   Rear Exhaust Unit Electrical Input Track—this interface allows the     Rear Exhaust Unit to rotate while receiving an uninterrupted power     supply of electrical current to power its electrical motor. #7 -   Rear Exhaust Unit—after passing through an extended set of turbine     blades, the combustion gasses are channeled into this rotatable unit     that assists in propulsion, climbing, diving, braking, hovering and     VTOL/STOL operations. Thrust is adjustable because the CPU     calculates and regulates the amount of compressed air and fuel     burned in the jet engines' combustion chambers to fit the situation     at hand. #8 -   V.A.P./S. Unit Base—securely attached to the fuselage, it is the two     point pathway through which the power from the Burner Unit's     jet/rocket thrust is passed on to the rest of the aircraft where it     will be used to lift, propel, steer, stabilize, brake, hover, and     land. Different shapes/fittings may be employed to various parts of     the V.A.P./S. Unit Base to reduce drag. #9 -   V.A.P./S. Unit Extension Shaft—the angle at which it is set     determines the proportion of thrust, produced within the Burner     Unit, allocated to steering and stabilization when maneuvers are     made. The angle may be adjusted, in flight, as total mass and speed     change. Different shapes/fittings may be employed to various parts     of the V.A.P./S. Extension Shaft to reduce drag. The shape     modifications may be fixed, or may rotate along with the Burner     Unit. Front and/or trailing edge tapering would be one possibility.     #10 -   V.A.P./S. Jet/Rocket Burner Unit—compressed air (and/or liquid     oxygen) and fuel are delivered separately and then mixed in the     V.A.P./S. Burner Unit where it is ignited, thereby producing the jet     thrust that lifts, propels, steers, stabilizes, brakes, and lands     the aircraft. While capable of revolving in any direction, depending     on what function is desired, during flight mode, though all four     units rotate on different planes, movement is simultaneous and     equivalent. Thrust is also variable because the CPU constantly     calculates and regulates the total amount of compressed air (and/or     liquid oxygen) available to all of the V.A.P./S. Burner Units,     collectively, and further distributes between the front set and the     rear set as needed. Fuel amounts are simultaneously delivered in the     appropriate ratios. The exhaust outlets of the Burner Units are     adjustable such that the speed and volume of the escaping gasses are     also variable depending upon the particular operation desired. #11 -   V.A.P./S. Unit—is comprised of the V.A.P./S. Unit Base, V.A.P./S.     Unit Extension Shaft, and the V.A.P./S. Jet/Rocket Burner Unit. #12     Power Allocation: Steering vs. Stabilization     FIG. 2A-Power Allocation: Steering vs. Stabilization—Straight/Full     Turn     FIG. 2B-Power Allocation: Steering vs. Stabilization—Full Turn

The Variably Angled Propulsion/Steering System (V.A.P./S.) is predicated upon a simple concept: the power generated by the engine(s) can and should be used to do more than just propel the craft forward. In conventional modern aircraft design, this is the only function an engine, and the thrust therefrom, serves. When a change of direction is required, the method by which this is accomplished has remained essentially unchanged using a combination of ailerons, rudder(s), and elevator(s) which rely solely on the passive manipulation of air flow. Even so-called thrust vectoring propulsion systems as would be found on the F-22, or SU-37 vector thrust along only one plane of motion and would play no role in counteracting the destabilizing forces of momentum upon an aircraft during sharply angled, high-speed maneuvers were such maneuvers to even be possible with these systems. During this process of redirection the formidable force of momentum (mass×speed) in addition to the ongoing uni-directional thrust of the engine(s) must be taken into account as they are both working in opposition to any sort of redirection. The more effectively we can counter and negate these great physical forces, the more maneuverable the aircraft becomes. In a military context, this becomes a matter of life and death—victory and defeat! Would it stand to reason that a more maneuverable aircraft is a more survivable aircraft? So now the question becomes, “How to produce a more maneuverable aircraft?”

We must first ask ourselves, “What is the greatest force that a jet aircraft has available to in some way actively mitigate the destabilizing forces of momentum levied against the aircraft as it attempts to change direction?” If we adopt the conventional wisdom the answer would be drag (friction) and pressure differential. Now stop and think; if that was such a potent force, “Why not use it to propel the craft in the first place?” The answer is simple; drag and pressure differential are not generative forces, but rather associative forces. That is to say that they exist only by gently “tapping into” an existing generative force—in this case momentum. As stated earlier, momentum is the product of mass and speed. Without a force to generate speed, the aircraft will not fly, nor will it turn. It should be clear that drag and pressure differential are not the greatest forces available. I'm quite sure that you had already reasoned as much. I'd also venture to say that you have figured out what is the greatest force an aircraft has available to it. Now the question becomes, “How to most effectively harness the power of jet thrust?” This brings us squarely to the essence of the V.A.P./S.}

The Variably Angled Propulsion/Steering System (V.A.P./S.) is predicated upon a simple concept: the power generated by the engine(s) can and should be used to do more than just propel the craft forward. This decentralized yet coordinated array of units produce thrust which is vectorable on an infinite number of planes (when combined with the Rear Exhaust Unit) thus providing integrated and seamless propulsion, steering, and stabilization of the aircraft, as well as hovering, braking and vertical (or short) take-off and landing.

The Burner Units, which house the combustion chambers (the source of the thrust), are fully rotatable along variable, changeable planes ranging from parallel to perpendicular. The incline, or decline, of the V.A.P./S. Unit Extension Shaft (depending on whether the V.A.P./S. Unit is located towards the front, or back of the aircraft) determines the plane of rotation of the Burner Unit. In FIG. 2A and FIG. 2B a 0 degree positioning of the V.A.P./S. Extension Shaft represents a perpendicular plane of Burner Unit rotation. If all (in this case four) of the V.A.P./S. Extension Shafts were to be in this position during flight mode, 100% of the available jet thrust would be applied towards stabilization during maneuvers. In the same illustration+ or −90 degrees (depending on whether the V.A.P./S. Unit is located towards the front, or back of the aircraft) represents a parallel plane of Burner Unit rotation. If all of the V.A.P./S. Extension Shafts were to be in this position, 100% of the available jet thrust would be applied towards steering (redirection). In FIG. 2A and FIG. 2B the Extension Shafts are set at 45 degrees (plus and minus, respectively) whereby equal amounts of thrust are applied towards both steering and stabilization, however, any setting between 0 degrees and + or −90 degrees is possible. We now have the two essential ingredients in place—the ability to apply the precise proportion of jet thrust needed towards 1) redirecting the aircraft, and 2) stabilizing the aircraft against the resulting forces of momentum. *Changes in the angle of the V.A.P./S. Unit Extension Shaft can be made in flight, as the variables of mass and speed change, as long as the Burner Unit(s) is completely straight during such adjustments.

Comparisons:

Conventional Jet Propulsion Systems—apply thrust in only one direction (forward propulsion); no steering capacity; no stabilization capacity.

Limited Thrust Vectoring Systems (F-22; SU-37)—apply thrust towards forward propulsion and assists in vertical attitude adjustment only; no stabilization capacity. V.A.P./S. System—applies thrust in any direction, and on any plane thus facilitating vertical take-off and landing and attitude adjustment (with the addition of the Rear Exhaust Unit), hovering, and braking, as well as forward propulsion, steering, and integrated stabilization such that no additional measures are necessary during sharply angled, high-speed maneuvers provided the Extension Shafts are set at an appropriate angle; the rotation of the Burner Units will temporarily eliminate the continuation of forward thrust while applying variable proportions of thrust to both steering and stabilization until the maneuver is complete, at which time forward propulsion (or any other function) may resume.

Conclusions

The V.A.P./S. System (applied to suitable aircraft) will enable more versatile, deployable, and maneuverable aircraft equipped than any other propulsion system making it more useful tactically and strategically, and any suitable aircraft to which it would be applied more survivable preserving both lives and material resources.

Unit Base #9 -   V.A.P./S. Unit Extension Shaft #10 -   V.A.P./S. Jet/Rocket Burner Unit #11 -   Central Axis of Rotation—a point that is halfway between the port     and starboard boundaries of the fuselage, and halfway between the     front and rear V.A.P./S. Units. #13     An extreme turn may be performed in the following manner:

Both front V.A.P./S. Burner Units revolve 90 degrees in the same direction as one another, but on different planes and at the same rate.

Simultaneously both rear V.A.P./S. Burner Units revolve in the same direction as one another (in the opposite direction as the two front V.A.P./S. Burner Units), but on different planes and at the same rate.

This procedure will cause the aircraft to rotate on its Central Axis. A correct angular setting of the V.A.P./S. Extension Shafts will allocate sufficient thrust to counteract destabilizing forces while the turn is being completed. The aircraft should rotate slightly beyond the intended direction at which point all of the V.A.P./S. Burner Units will briefly straighten so that the thrust of all of the V.A.P./S Burner Units, as well as the Rear Exhaust Unit, will directly oppose the force of momentum thus reducing slip angle. A very slight correction, whereby the V.A.P./S. Burner Units are very quickly and slightly rotated opposite the initial direction of rotation should be made at a point where the slippage has ceased. The V.A.P./S. Burner Units should then immediately return to full propulsion mode. When this maneuver is well practiced and well executed, the aircraft will be capable of near 90 degree turns. The placement of the Cockpit is such that the pilot is almost precisely aligned with the Central Axis of Rotation thus drastically reducing gravitational forces against the pilot while maintaining the perception that a turn has been made and to what extent.

Jet/Rocket Burner Unit Electromagnetic Actuating Gear—the     purpose here is to allow the V.A.P./S. Extension Shaft to change its     angle, and therefore the ratio of power allocated to propulsion and     steering, without affecting the linkage responsible for the rotation     of the V.A.P./S. Jet/Rocket Burner Unit. This is feasible because     all systems are routed through either the primary C.P.U., or the     local V.A.P./S. Jet/Rocket Burner Unit C.P.U.'s. In this instance     both steering and angular adjustments would be overseen by the     primary C.P.U. which would be programmed to halt electrical current     to this gear when the V.A.P./S. Extension Shaft is making     adjustments so that the V.A.P./S. Jet/Rocket Burner Unit     Electromagnetic Receptor Gear would be able to “slip” freely without     affecting the linkage that rotates the V.A.P./S. Jet/Rocket Burner     Unit. Once the V.A.P./S. Extension Shaft adjustment is complete the     electrical current sent to the V.A.P./S. Jet/Rocket Burner Unit     Electromagnetic Actuating Gear is resumed so that steering is again     enabled. *The Burner Unit(s) must be positioned for straight flight     before the angular setting of the V.A.P./S.

Burner Unit Alternator/Generator. #22 -   V.A.P./S. Burner Unit Alternator/Generator—provides power for     various components within the V.A.P./S. Burner Unit such as the     C.P.U., Exhaust Piston Motor, feedback sensors, injectors, and the     igniting element for the V.A.P./S. Combustion Chamber during     start-up. An auxiliary battery, to be used when the Burner Unit is     in rocket mode, is integrated so that it will always remain fully     charged when not in use. #23 -   V.A.P./S. Burner Unit C.P.U.—controls those functions local to the     V.A.P./S. Burner Unit such as electrical current routing, and     Exhaust Piston positioning based upon sensory feedback and     programming. #24 -   V.A.P./S. Burner Unit Speed Sensor—provides the C.P.U. with the     current velocity of the aircraft so that the C.P.U. may use that     factor to help determine the optimal positioning for the Exhaust     Piston and the V.A.P./S. Extension Shaft. #25 -   V.A.P./S. Burner Unit C.P.U. Deflected Cooling Vent—inlet for air to     cool the C.P.U. in a tempered manner. #26 -   V.A.P./S.

Burner Unit Cooling Vent Outlet #26B -   V.A.P./S. Burner Unit Generator Routing Switch—through communication     with the C.P.U. this switch directs electrical current from the     V.A.P./S. Burner Unit Alternator/Generator to the Exhaust Piston     Motor, V.A.P./S. Burner Unit Combustion Chamber Electrical Hub,     sensors and the CP.U. itself. #27 -   V.A.P./S.

Burner Unit     Alternator/Generator Routing Switch. #29 -   Exhaust Piston Motor Relay Line—delivers electrical current to the     Exhaust Piston Motor Relay Switch. #29A -   Exhaust Piston Motor Relay Switch—as directed by the C.P.U.,     electrical current may flow to one of three channels—outward, stop,     and inward so that the Exhaust Piston may be positioned properly.     When electrical current is directed towards either outward or     inward, it must first pass through the stop channel at which point a     brake is applied before current is redirected to the opposite     channel. This allows the Exhaust Piston Motor Output Gear to very     briefly stop before reversing its direction of rotation. If the     reversing of the Exhaust Piston Motor Output Gear can be effectively     accomplished without braking and stopping, and done so in a     sustained manner, then the intermediate stop channel may be     eliminated. #30 -   Exhaust Piston Motor—operates the Exhaust Piston Motor Output Gear     in both directions of rotation. #31 -   V.A.P./S Exhaust Piston Motor Output Gear—actuates the Exhaust     Piston Rack to which the Exhaust Piston is attached. #31A -   V.A.P./S Exhaust Piston Rack—as it is moved inward and outward by     the Exhaust Piston Motor Output Gear, so to is the Exhaust Piston.     #32 -   V.A.P./S Exhaust Piston Rack Sensor—provides the C.P.U. with the     precise positioning of the Exhaust Piston Rack (and therefore the     Exhaust Piston) so that adjustments made to the Exhaust Piston are     made relative to its current position. #32A -   V.A.P./S Exhaust Piston Rack Sensor Feedback Line—the means by which     feedback from the Exhaust Piston Rack Sensor is transmitted to the     C.P.U. #32B -   V.A.P./S Exhaust Piston Rack Guide #33 -   V.A.P./S Exhaust Piston—the area of the V.A.P./S. Exhaust Nozzle is     varied according to the position of the Exhaust Piston enabling the     manipulation of thrust. Hatched area (the part that remains within     the Exhaust Piston Cylinder at all times) is more dense than the     unhatched area of the Exhaust Piston to provide a favorable balance     when the Exhaust Piston is fully extended. #34 -   V.A.P./S Exhaust Piston Bearings—facilitates the smooth back and     forth passage of the Exhaust Piston within the Exhaust Piston     Cylinder. #34A -   V.A.P./S Exhaust Piston Cylinder—housing in which the Exhaust Piston     resides. #34B -   V.A.P./S Exhaust Piston Cylinder Cooling Fins—transfers heat from     the Exhaust Piston Cylinder so that it may be vented by the flow     through of air. #35 -   V.A.P./S. Double Walled Vacuum Return Fuel Line—fuel flows through     the inner tubing while a vacuum leading back to the fuel tank exists     between the inner and outer tubing to eliminate the possibility of     leakage into the V.A.P./S. Compressed Air Conduit. #36 -   V.A.P./S. Burner Unit Fuel Reservoir—provides a convenient means by     which the fuel supply may be disbursed to the multiple V.A.P./S.

-   V.A.P./S. Combustion Chamber—fuel is mixed and burned with     compressed air in jet mode, liquid oxygen in rocket mode, or     compressed air supplemented by liquid oxygen for super bursts of     speed and power, further enhancing the hyper-agility the V.A.P./S.     System provides to aircraft to which it is applied. *The hybrid     nature of this combustion process would enable this aircraft to     climb to the upper atmospheric layer in jet mode, exit the     atmosphere and enter a low orbit in rocket mode, and travel to the     opposite side of the planet in a fraction of the time it would have     taken otherwise, thus dramatically increasing the ability to project     power in a crisis. #38 -   V.A.P./S. Combustion Chamber—Lower #38A -   V.A.P./S. Unit Variable Area Exhaust Nozzle—the exhaust escape area     is varied with the extension and retraction of the Exhaust Piston.     #38B -   V.A.P./S.

Hatched area (the part     that remains within the Rear Exhaust Piston Cylinder at all times)     is more dense than the unhatched area of the Rear Exhaust Piston to     provide a favorable balance when the Rear Exhaust Piston is fully     extended. #42 -   Rear Exhaust Piston Rack—attached to the Rear Exhaust Piston, it is     actuated by the Rear Exhaust Unit Motor Output Gear. #42A -   Rear Exhaust Piston Rack Guide #42B -   Rear Exhaust Piston Rack Sensor—provides feedback to the main C.P.U.     so that all adjustments to the Rear Exhaust Piston take into account     its current position. #42C -   Rear Exhaust Piston Rack Sensor Feedback Line—sends and receives     sensory feedback information to and from the primary CPU via the     Rear Exhaust Piston Rack Sensor Feedback Roller. #42D -   Rear Exhaust Piston Rack Sensor Feedback Roller—sends and receives     uninterrupted sensory feedback information to and from the main     C.P.U. regardless of movements by the Rear Exhaust Unit itself. #42E -   Rear Exhaust Piston Cylinder #42F -   Rear Exhaust Piston Cylinder Ball Bearings—completely encircle Rear     Exhaust Piston, front and back, to facilitate smoother back and     forth passage of the Exhaust Piston. #42G -   Rear Exhaust Unit Variable Area Exhaust Outlet #43 -   Rear Exhaust Unit Motor—drives the Rear Exhaust Unit Motor Output     Gear. #44 -   Rear Exhaust Unit Motor Output Gear—adjusts the position of the Rear     Exhaust Piston Rack and therefore the Rear Exhaust Piston. #44A -   Rear Exhaust Unit Motor Relay Switch—receives instructions from the     main CPU via the Rear Exhaust Piston Rack Sensor Feedback Roller and     routes electrical current to one of three channels which feed the     Rear Exhaust Unit Motor (clockwise rotation, off/brake,     counter-clockwise rotation). *The off/brake channel may be     eliminated if tests show that mechanical reliability and longevity     are not compromised. #44B -   Rear Exhaust Unit Motor Electrical Receptor—delivers electrical     current from the Rear Exhaust Unit Electrified Track to the Rear     Exhaust Unit Motor Relay Switch. #44C -   Rear Exhaust Unit Feedback Track—allows for a continuous flow of     sensory feedback to and from the main C.P.U. as the Rear Exhaust     Unit rotates up and down. #45 -   Rear Exhaust Unit Electrified Track—allows for a continuous flow of     electrical current to the Rear Exhaust Unit Motor as the Rear     Exhaust Unit rotates up and down. #46 -   Rear Exhaust Unit Adjuster Gear—initiates the upward and downward     rotation of the Rear Exhaust Unit Receptor Gear. #47 -   Rear Exhaust Unit Receptor Gear—effects the upward and downward     rotation of the Rear Exhaust Unit. #48 -   Rear Exhaust Unit Vacuum—heat barrier. #49     V.A.P./S. Flight Modes     FIG. 6A-V.A.P./S VTOL Mode—the aircraft begins in Vertical Take-Off     and Landing mode. It may be desirable to equip the aircraft with     landing gear which may be utilized when a vertical take-off, or     vertical landing are not required. This will save fuel extending the     aircraft's range, but more importantly will enable a heavier than     normal payload. When landing, after the target landing area has been     reached with the Rear Exhaust Unit and all four of the V.A.P./S.     Burner Units aligned vertically, exhaust nozzles pointed downwards,     thrust is gradually reduced such that the aircraft will begin a     controlled descent. The CPU will apportion air and fuel so that the     appropriate balance in thrust is maintained for a quick, controlled     descent. Should minor positioning adjustments be desired during     descent the Lateral/Pivoting Control System will vent a small     portion of the compressed air within the Air Distribution Chamber in     the appropriate direction until the desired adjustment is complete.     FIG. 6B-V.A.P./S. Transitional Mode—once an adequate altitude has     been attained, the V.A.P./S. Burner Units and the Rear Exhaust Unit     begin to rotate such that they are both lifting and propelling the     aircraft forward.     FIG. 6C-V.A.P./S. Flight Mode [Start]—once an adequate speed has     been attained, the V.A.P./S. Burner Units and the Rear Exhaust Unit     continue to rotate until they are parallel to the body of the     aircraft and are propelling the aircraft forward.     FIG. 6D-V.A.P./S. Flight Mode [Full]—at the moment the V.A.P./S.     Burner Units reach Flight Mode [Start] position, the V.A.P./S. Unit     Extension Shafts begin to ascend in the front, and descend in the     rear to an optimal, matching angle (see diagram Power Allocation:     Steering vs. Stabilization). -   Rear Exhaust Unit #8 -   V.A.P./S.

Braking Start—From full flight mode, the V.A.P./S.     Unit Extension Shafts readjust position to the same plane as the     body of the aircraft (0 degrees; see FIG. 2A) while the V.A.P./S.     Burner Units continue to propel the aircraft in a straight, forward     path.     FIG. 7B-V.A.P./S. Braking Stage 1—once the V.A.P./S. Unit Extension     Shafts readjust to 0 degrees, the two front V.A.P./S. Burner Units     and the Rear Exhaust Unit begin to rotate in the same direction at     the same rate. The CPU, through sensory feedback will regulate the     air and fuel supply, and apportion these such that thrust produced     in the two rear V.A.P./S. Burner Units is minimized in favor of the     two front V.A.P./S. Burner Units and the Rear Exhaust Unit. This is     accomplished by allowing increased airflow through to the combustion     areas within the two main fuselage mounted jet engines while     simultaneously diverting more air allocated for the V.A.P./S. Burner     Units to the two front V.A.P./S. Burner Units. Thrust is monitored     as needed so that there are equal and opposing forces acting upon     both ends of the aircraft (factoring in the leverage advantage of     the Rear Exhaust Unit).     FIG. 7C-V.A.P./S. Braking Stage 2—the two front V.A.P./S. Burner     Units and the Rear Exhaust Unit continue to rotate until they have     both reached a vertical orientation, perpendicular to the fuselage,     exhaust nozzles pointing downward.     FIG. 7D-V.A.P./S. Braking Stage 3—at the moment a vertical     orientation has been reached, the Rear Exhaust Unit begins to     reverse direction while the two front V.A.P./S. Burner Units     continue in their original direction of rotation. Each continues to     rotate at the same rate (a micro delay in motion for the two front     V.A.P./S. Burner Units may be necessary if there is any mechanical     delay as the Rear Exhaust Unit changes its direction of rotation).     FIG. 7E-V.A.P./S. Braking Stage 4—the two front V.A.P./S. Burner     Units, having completed 180 degrees of rotation, and directly     opposing the two rear V.A.P./S. Burner Units and the Rear Exhaust     Unit, will now receive air and fuel in the maximum quantities at the     expense of the two rear V.A.P./S. Burner Units and the Rear Exhaust     Unit at a rate that will produce a well targeted landing position as     calculated by the CPU taking into account factors including, but not     limited to, velocity of aircraft, mass of aircraft, wind direction     and speed, distance to target area, etc. -   Rear Exhaust Unit #8 -   V.A.P./S.

The arrows in the illustration indicate the direction of gravitational force that would be levied against the linkage by the V.A.P./S. Units if they were not secured. As shown, the Right/Front and the Right/Rear V.A.P./S. Units (as well as the Left/Front and Left/Rear Units) cancel each other and therefore are unable to set the connective linkage into motion. The End Drive Shaft Brace is simply an added layer of protection. “X” indicates the point at which forces cancel one another eliminating feedback motion through the angling linkage.

The arrows in the illustration indicate the direction of thrust force that would be levied against the linkage by the V.A.P./S. Units, during maneuvers, if they were not secured. As shown, the Right/Front and the Right/Rear V.A.P./S. Units (as well as the Left/Front and Left/Rear Units) cancel each other and therefore are unable to set the connective linkage into motion. The End Drive Shaft Brace is simply an added layer of protection. “X” indicates the point at which forces cancel one another eliminating feedback motion through the angling linkage.

Units (necessary     during the braking process). #57A -   V.A.P./S Angling Gear #58 -   V.A.P./S Angling Gear Actuated Splined Recess #58A -   End Drive Shaft Stem Rack Gear—rotates at approximately twice the     speed as the End Drive Shaft so that the End Drive Shaft Stem Rack     may successfully engage the End Drive Shaft Splined Bracing Insert     with the End Drive Shaft Splined Bracing Receptor. #59 -   End Drive Shaft Stem Rack #60 -   End Drive Shaft Stem Rack Spindle—allows the End Drive Shaft     Actuating Splined Insert to spin freely while the End Drive Shaft is     moved in either direction. #60A -   V.A.P./S Angling Shaft (Stage 1) #61 -   V.A.P./S Angling Receptor Gear #61A -   V.A.P./S Angling Actuating Gear #61B -   V.A.P./S Angling Shaft (Front, Stage 2)—transmits motion to adjust     the angling of the front V.A.P./S. Units. #62 -   V.A.P./S Angling Gear (Front, Stage 2) #62A -   V.A.P./S Angling Shaft (Rear, Stage 2)—transmits motion to adjust     the angling of the rear V.A.P./S. Units. #63 -   V.A.P./S Angling Gear (Rear, Stage 2) #63A     Turbine/Compressor Gearings     FIG. 9A—Turbine Compressor Gearings (Cut Away)     FIG. 9B—Turbine Compressor Gearings (Cross Sectional) -   Turbine Shaft—driven by an extended series of turbine blades. -   Compressor Shaft—driven by the Turbine Shaft (via a series of     multiplying gears), it revolves more than once for every one     revolution of the Turbine Shaft. In the illustrated example,     approximately 2:1. -   Turbine Multiplying Gear—one revolution of this gear results in     multiple revolutions of the Compressor Gear via the Turbine     Intermediate Gear. The purpose is to maximize the volume of     compressed air delivered to the V.A.P./S. Burner Units as well the     combustion chambers of the primary jet engine(s) itself. It is     possible due to the extended length of each of the jet engines which     allows for additional series of axial turbine blades which extract     more power from the expanding gasses escaping the combustion     chambers thereby providing the additional torque required. -   Turbine Intermediate Gear—driven by the Turbine Multiplying Gear it     actuates the Compressor Gear. In this arrangement, it allows for     both the Turbine Shaft and the Compressor Shaft to remain inline     with one another, thereby providing the most economical     configuration. -   Compressor Gear—driven by the Turbine Multiplying Gear (via the     Turbine Intermediate Gear), as it revolves so to does the Compressor     Shaft to which are attached a series of compressor blades.     V.A.P./S. Air Intake Feed (Top View)     FIG. 10—V.A.P./S. Air Intake Feed (Top View) -   Compressed Air—from the Air Distribution Chamber. -   V.A.P./S. Air Intake Feed Diverter—assists the compressed air to     divide more easily. -   V.A.P./S. Air Intake Feed Valve—apportions the compressed air     between the front and back V.A.P./S. Units. -   72} V.A.P./S. Air Intake Cylinder—delivers compressed air to the     V.A.P./S. Units where it is routed to the Burner Units and then to     the Combustion Chambers.     Air Distribution Unit (Top & Cross Section)

This unit is optional, as compressed air may be routed directly from each of the main jet engines' compressors to the V.A.P./S. Distribution Cylinders and ultimately on to the V.A.P./S. Burner Units. Its inclusion, however, does afford the following advantages: Airflow to the V.A.P./S. Burner Units may be more efficiently monitored and distributed by the CPU if that airflow emanates from one centralized source.

If there is any difference in the compressor output of any of the engines, the airflow to each of the individual V.A.P./S. Burner Units would remain uniform (unless operations/maneuvers dictated a disproportionate allocation as regulated by the CPU). Fully pivoting venting units, utilizing a small portion of the compressed air, would allow the aircraft to make lateral adjustments, particularly useful during VTOL operations, and to pivot in a clockwise, or counter-clockwise direction while hovering; also useful to lock and fire on multiple targets while hovering.

The presence of the Air Distribution Chamber would make it possible to eliminate the auxiliary starter engine by filling the chamber with highly compressed air prior to take-off. This air would then be released to the burner sections of the main engines wherein fuel would be added and mixed in the presence of an igniting element. If the mission repertoire includes low-orbit, trans-global deployment then the main jets would at some point, temporarily, discontinue operation. Prior to this planned shut down, the Air Distribution Chamber outlets would be closed while the Compressed Air Intake(s) would remain open causing the already compressed air entering to become super compressed. When the pressure within the Air Distribution Chamber nears the pressure threshold, the Compressed Air Intake(s) would also close as the main engines shut down. This store of super compressed air would provide the available source of compressed air to re-ignite the main engines after orbital re-entry, after which normal operations would resume. *From the period between exit and re-entry into the atmosphere, liquid oxygen and fuel would then be fed to the Combustion Chambers within each Burner Unit. The versatile application of thrust in any direction and at any angle, afforded by the V.A.P./S. System, would allow the Burner Units to apply a sustained braking counter-thrust as the aircraft descended from orbit in a controlled manner. While in orbit, the same maneuvering capabilities as is possible within the atmosphere would exist (at a faster rate) opening up a myriad of possible tactical, strategic, and defensive applications.

*Arrows indicate the direction of compressed airflow in FIGS. 11A and 11B.

FIG. 11A—Air Distribution Unit (Top)

FIG. 11B—Air Distribution Unit (Cross Section)

-   Turbine Compressor Section—having an internal valve (not shown),     which is controlled by the CPU, it determines the proportion of     compressed air delivered to the Air Distribution Chamber and the     proportion allowed to flow through to the primary jet engine's     combustion chambers.     Compressed Air Intake (for the Air Distribution Chamber) -   Entry Diverter—allows compressed air from both compressors to blend     more smoothly. *It may be desirable to incorporate some type of     supplemental ram intake for certain applications of the V.A.P./S.     System. In such a case, a one-way valve could be incorporated     whereby the sufficiently compressed air from the ram intake might     enter the Air Distribution Chamber through the Entry Diverter at a     point of least resistance, thereby increasing the total available     mass of compressed air while still allowing the aircraft's primary     C.P.U. to account for all of the available compressed air and     maintain more precise allocations to each of the Burner Units     according to the situation at hand. -   Exit Diverter—allows compressed air from Air Distribution Chamber to     exit more smoothly. -   V.A.P./S. Distribution Cylinder Diverter—allows compressed air from     the Air Distribution Chamber to separate more smoothly. -   V.A.P./S. Distribution Cylinder Apportioning Valves—governed by the     CPU, these valves operate independently of one another and regulate     the proportion of compressed air delivered to each of the four     V.A.P./S. Units. The amount of fuel injected into the V.A.P./S.     Burner Units' combustion chambers is adjusted by the CPU     accordingly. -   V.A.P./S. Distribution Cylinder—delivers compressed air to the     V.A.P./S. Units. -   Air Distribution Chamber—collects compressed air from both axial     compressors and distributes it to both V.A.P./S. Distribution     Cylinders. Even if one of the jet engines became inoperative, while     there would be a 50% decrease in total power output, the aircraft     would be able to maintain controlled flight. -   80A) V.A.P./S. Air Distribution Chamber Outlet -   80B) V.A.P./S. Distribution Chamber Bridge—contained within the hull     of the aircraft, it delivers compressed air from the Air     Distribution Chamber to the V.A.P./S. Distribution Cylinder. -   80C) V.A.P./S. Chamber Bridge Compressed Air Outlet     Lateral/Pivoting Control System     FIG. 12A-Counter Clockwise     FIG. 12B-Left/Right     FIG. 12C-Clockwise     Air Distribution Chamber -   Venting Units—are able to rotate 360 degrees (although no more than     270 degrees of rotation would suffice) venting a small portion of     the compressed air in opposite directions while pivoting. To effect     lateral movement compressed air may be released from one Venting     Unit, or from both Venting Units aligned in the same direction. Fore     and aft adjustments (and any other directional movements) to the     aircraft are equally feasible. -   Compressed Air—is vented through valves (not shown) from fully     rotatable nozzles effecting lateral and pivoting maneuvers.     Double-Walled Vacuum Fuel Line and Fuel Coupling     FIG. 13-Fuel Line (not to scale) without any separation and numbered     parts. *For an overview see FIG. 4, parts 36, 37, 37A. -   Fuel Tank -   Fuel Tank Outlet -   Nozzle Seat—one of a number of acceptable methods to link one     section of Fuel Line with another. -   Fuel Line Joint—if there is any fuel leakage (slight if any), it     will not be permitted to escape into the Compressed Air Conduit due     to a double layered line and a constant vacuum that returns droplets     and/or fumes to the fuel tank (exemplified in FIG. 13, adjacent to     the Fuel Line Joint). -   Inner Housing—primary carrier of fuel to the Burner Unit's     combustion chambers. -   Vacuum Wall Housing—creates a barrier between the Fuel Line     (especially at its joints) and the Compressed Air Conduit. -   Fuel Line Vacuum Conduit—pathway through which any leakage     (droplets, fumes) is returned to the Fuel Tank via a vacuum. -   Fuel Line Vacuum—revolving blades create a pressure differential on     either side of it causing the air to flow towards the Fuel Tank. -   Uni-Directional Valve—if enough fuel has leaked over an extended     period of operation the two stage valve will allow fuel to return     yet not exit (exemplified in FIG. 13 entering through the first     stage of the Uni-Directional Valve, and again through the second     stage of the Uni-Directional Valve into the Fuel Tank).

An alternative configuration of the invention within the scope of the claims that follow may incorporate a Burner Unit at the tip of each wing that is rotated up and down, each one opposite the direction of the other. Yaw control may be accomplished by conventional rudder and/or by placing a Burner Unit at the rear that is rotated left and right. The effect would be steering or yaw impetus at the rear, and roll control on both sides. Pitch control can be conventional, or augmented by having the same or other rear Burner Units that are rotated up and down.
